STS134: Third spacewalk complete

247th US spacewalk.

During the third spacewalk of the STS134 mission, mission specialists Drew Feustel and Mike Fincke completed a series of modifications to the station that will allow the ISS to perform more efficiently when the shuttles are retired.

Modifications were made to the Russian Zarya module so that a bcakup solar power system is available, and a new base was created for attaching the station's CanadArm-2 to the module, thus extending its reach. The two astronauts also completed some communications maintenance on the exterior of the station.
